Be it known thatfI, LEWis K, DAvis,.a

Indianapolis, Indiana, have invented certain'4 new and usefulImprovements in Retaining- 'Wallsk for Reservoirs, of which thefollowing ,is

' ia specification, accompanied by drawings.

This invention relates to'masonr l walls but more particularlyto-'retaining-Wallsfor reservoirs; and its objects kare to" improve yupon the Vconstruction of such walls, increase.y

their strength, andyreduce the costl kof 'construction. i f

'i f Further objects ofthe invention will hereinafternappeam and tovthese ends theinyen-j "tion .consists ofk a retaining-wall for. carryingouty the above objects :embodying the fea- .tures of construction,`combinations "fof,` eleenlarged scalev dn the.

utilized in anyy connectionfin which .it is -found'app,licable, I haveshown it as applied to areservoir in which A is the reservoir-bed, whichmay be of any -suitable construction.

, The wall is constructed ofhollow bricks or,`

tiles B, which may or inaynot be provid ed i with-the, perforationsvCfinj-the sides, and

`these bricks B are arranged with their 'aperturesD in averticaldirection, as shown in Preferably the tbricks are. arranged 'y to breakjoint., and the ends ofthe bricksa'rfe` recessed, as at E.,andthroughall 'of the a' erv tures D and recesses E strengthening ro sor.`

bars F are arranged. 1 Suitable forms` G are y applied ateach side ofth'ejoints, 'and then el apertures D and recesses E are filled with asuitable bituminous filler-as, for instance,v

` as at I, and embedded in the base A of ther bituminous concrete H:'v'lhe lower endsof thezstrengtheningerods F are preferably bent,

a top layer i may be provided of. concrete,y whichv strengthening-rodsareembedded, and, as shown in Fig.l 1, the

strengthening-rodsF maybe extended-up `r wardly into the top layer J,.thereby servingl tobindv the saine to the main structure. If i ireservoir, L'willV represent the inside of lthe I Wall .and O the`outside surface, to which the 'retaining4wall isl toV vservev as' thewall. of .a

outer surface -a layer P, of concre'te may be be oinittedn 1 cyAccording to, this invention the retainingwall is provided. with ayconcrete bracing inl although thislayer may` theform of a strut Q,arranged at an angle to the main portion-of. the wall and connected tothe wall at oneportion of itsheight, as at the 7- upper end adjacent theupper layer J leaving Y,

an openspaceR, betweenthegstrutQand .the y "si'de'fthewall Strengtheningrods or'bars QS are shown embedded' in 'the concrete strut' Q, said'bars being bent at theirlower ends T any suitable manneras, forinstance, by

ythe use'of forms. `According to this con- 8o saving is made inthe-costof construction,l vi ystructioiiit will be seen that a very materialbecause the amountofniaterial necessary is greatly lessened and atthesame' time ay wall of increased strength is produced, owing to thecomposite structure of the saine, which is c Y A75 and embedded in thebase A ofthe structure. The concrete strut Q may be constructedinstrongly braced in the desired directions and.

bounditogether by the strengtliening-rods or j lThe bricks or tiles'Bmay be constructed different shapes,`asshown in Figs. 4 yand 5. .In

tie-rods, as described, with a strengtlieningfillerv ofbituminous-concrete.

Fig'.y 4 the bricks are shown interlocking one .with another,-eachvcbricky being, provided with a tongiie U, which interlocks withthe 5 recessed portion-`ofV the, adjacent brick, i* In Fig. 5 the bricksare shown withflateorriilgited ends V Which has been found toy be asuitable and efficient construction, yalthough lthe preferred form ofkconstruction is that shown in Fig. 4. y Y

.l` InFig. 16 an ,with the yforms ofy wall illustratedto make up thecoin lete wall. y. In theinstance of Fig. 6 four-oft ebricks or tilesare combined inthe ,iformof a 4hollow square, Vforming acolumn,

land a number of these hollow columns may bev incorporated at intervalsin the structure' Ico,4 i elementalconstruction for a.'` 4 columnis'shown, which mayl be combined of the wall. Preferably the end bricksof the columns are secured b expanded metal retainers or bandsW. sbefore, strengthening-rods F are varranged within the hollow portions ofthe bricks and in the central hollow portions of the columns,l Aand thena bituminous filler H is poured around the rods F within the hollowportions of the bricks and inthe hollow center of the columns.

This invention is not limited to any particular form 'of vfiller for theretaining-wall, for bituminous concrete or any other suitable filler maybe used, as desired.

Obviously some features of this invention maybe used without others, andthe invention may forms.

Therefore., without-limiting myself to the be embodied in widely-varyingconstruction shown and described nor enumerating equivalents, I claim,and desire to secure by Letters Patent, the following:

1. A retaining-wall for reservoirs and other uses, Comprising hollowbricks or tiles arranged in the form of hollow squares with lluaperturesin the bricks in vertical direction. strengthening-rods extendingthrough said apertures, and a bituminous filler around said rods in thehollow bricks and in the hollow squares, for substantially the purposesset forth.

2. A retaining-wall for reservoirs and other uses, comprising hollowbricks or tiles arranged with their apertures in a vertical direetion,and filled with a bituminous filler, and a concrete bracing for saidwall forming a strut connected to the wall at one portion with an openspace between the strut and the side of the wall7 for substantially thepurposes set forth.

In testimony whereof I have signed this .specification in the presenceof two subscribmg witnesses.
